commit 466476dfdcafbb4286ffa232a3a792731b9dc852 upstream.
This is slightly cleaned up version of Jerome's patch.
There seems to be an issue tracking the last flush of
the VM which results in hangs in certain cases when
VM is used. For now just flush the VM for every IB.

GMBUS based DVO transmitter detection seems to be unreliable which could
result in an unusable DVO port.

commit b6c5164d7bf624f3e1b750787ddb983150c5117c upstream.
Yet again our current confusion between doing the modeset globally,
but only having the new parameters for one crtc at a time.
So that intel_set_mode essentially already does a global modeset:
intel_modeset_affected_pipes compares the current state with where we
want to go to (which is carefully set up by intel_crtc_set_config) and
then goes through the modeset sequence for any crtc which needs
updating.
Now the issue is that the actual interface with the remaining code
still only works on one crtc, and so we only pass in one fb and one
mode. In intel_set_mode we also only compute one intel_crtc_config
(which should be the one for the crtc we're doing a modeset on).
The reason for that mismatch is twofold:
- We want to eventually do all modeset as global state changes, so
it's just infrastructure prep.
- But even the old semantics can change more than one crtc when you
e.g. move a connector from crtc A to crtc B, then both crtc A and B
need to be updated. Usually that means one pipe is disabled and the
other enabled. This is also the reason why the hack doesn't touch the
disable_pipes mask.
Now hilarity ensued in our kms config restore paths when we actually
try to do a modeset on all crtcs: If the first crtc should be off and
the second should be on, then the call on the first crtc will notice
that the 2nd one should be switched on and so tries to compute the
pipe_config. But due to a lack of passed-in fb (crtc 1 should be off
after all) it only results in tears.
This case is ridiculously easy to hit on gen2/3 where the lvds output
is restricted to pipe B. Note that before the pipe_config bpp rework
gen2/3 didn't care really about the fb->depth, so this is a regression
brought to light with

drm/i915: precompute pipe bpp before touching the hw
But apparently Ajax also managed to blow up pch platforms, probably
with some randomized configs, and pch platforms trip up over the lack
of an fb even in the old code. So this actually goes back to the first
introduction of the new modeset restore code in

commit dc652f90e088798bfa31f496ba994ddadd5d5680 upstream.
Backlight cleanup in the eDP connector destroy callback caused the
backlight device to be removed on some systems that first initialized LVDS
and then attempted to initialize eDP. Prevent multiple backlight
initializations, and ensure backlight cleanup is only done once by moving
it to modeset cleanup.
A small wrinkle is the introduced asymmetry in backlight
setup/cleanup. This could be solved by adding refcounting, but it seems
overkill considering that there should only ever be one backlight device.

commit 4615d4c9e27eda42c3e965f208a4b4065841498c upstream.
Enabling context support increases SwapBuffers latency by about 20%
(measured on an i7-3720qm). We can offset that loss slightly by enabling
faster caching for the contexts. As they are not backed by any
particular cache (such as the sampler or render caches) our only option
is to select the generic mid-level cache. This reduces the latency of
the swap by about 5%.
Oddly this effect can be observed running smokin-guns on IVB at
1280x1024:
Using BLT copies for swaps: 151.67 fps
Using Render copies for swaps (unpatched): 141.70 fps
With contexts disabled: 150.23 fps
With contexts in L3$: 150.77 fps

commit 7a7d1fb79fb581553f4830498045de774a9659f8 upstream.
The connector associated with the encoder is considered active when the
output associtated with this connector is active on the encoder. The
encoder itself is considered active when either there is an active
output on it or the respective SDVO channel is active.
Having active outputs when the SDVO channel is inactive seems to be
inconsistent: such states can be found when intel_modeset_setup_hw_state()
collects the hardware state set by the BIOS.
This inconsistency will be fixed in intel_sanitize_crtc()
(when intel_crtc_update_dpms() is called), this however only happens
when the encoder is associated with a crtc.
This patch also reverts:

commit e12a2d53ae45a69aea499b64f75e7222cca0f12f upstream.
The routine to query the base of stolen memory was using the wrong
registers and the wrong encodings on virtually every platform.
It was not until the G33 refresh, that a PCI config register was
introduced that explicitly said where the stolen memory was. Prior to
865G there was not even a register that said where the end of usable
low memory was and where the stolen memory began (or ended depending
upon chipset). Before then, one has to look at the BIOS memory maps to
find the Top of Memory. Alas that is not exported by arch/x86 and so we
have to resort to disabling stolen memory on gen2 for the time being.
Then SandyBridge enlarged the PCI register to a full 32-bits and change
the encoding of the address, so even though we happened to be querying
the right register, we read the wrong bits and ended up using address 0
for our stolen data, i.e. notably FBC.

commit 219b47339ced80ca580bb6ce7d1636166984afa7 upstream.
Currently we have a problem with this:
1. i915: create gem object
2. i915: export gem object to prime
3. radeon: import gem object
4. close prime fd
5. radeon: unref object
6. i915: unref object
i915 has an imported object reference in its file priv, that isn't
cleaned up properly until fd close. The reference gets added at step 2,
but at step 6 we don't have enough info to clean it up.
The solution is to take a reference on the dma-buf when we export it,
and drop the reference when the gem handle goes away.
So when we export a dma_buf from a gem object, we keep track of it
with the handle, we take a reference to the dma_buf. When we close
the handle (i.e. userspace is finished with the buffer), we drop
the reference to the dma_buf, and it gets collected.
This patch isn't meant to fix any other problem or bikesheds, and it doesn't
fix any races with other scenarios.
v1.1: move export symbol line back up.
v2: okay I had to do a bit more, as the first patch showed a leak
on one of my tests, that I found using the dma-buf debugfs support,
the problem case is exporting a buffer twice with the same handle,
we'd add another export handle for it unnecessarily, however
we now fail if we try to export the same object with a different gem handle,
however I'm not sure if that is a case I want to support, and I've
gotten the code to WARN_ON if we hit something like that.
v2.1: rebase this patch, write better commit msg.
v3: cleanup error handling, track import vs export in linked list,
these two patches were separate previously, but seem to work better
like this.
v4: danvet is correct, this code is no longer useful, since the buffer
better exist, so remove it.
v5: always take a reference to the dma buf object, import or export.
(Imre Deak contributed this originally)
v6: square the circle, remove import vs export tracking now
that there is no difference

commit e127dc28cc3057575da0216cde85687153ca180f upstream.
Backlight hotkeys weren't working before on certain cedartrail laptops.
The source of this problem is that the hotkeys' ASLE opregion interrupts
were simply ignored. Driver seemed to expect the interrupt to be
associated with a pipe, but it wasn't.
Accepting the ASLE interrupt without an associated pipe event flag fixes
the issue, the backlight code is called when needed, making the
brightness keys work properly.

FDO bug #62775
This needs to be backported to both 3.7 and 3.8 stable trees. Doesn't apply straight,
but it's a quick change.

This change properly enables the "requester" in G200ER cards that is

commit a8ec3a662921220fc058ed6f7f3674697876d218 upstream.
If first drm_open fails, the error-handling path will
incorrectly restore inode's mapping to NULL. This can
cause the crash later on. Fix by separately storing
away mapping pointers that drm_open can touch and
restore each from its own respective variable if the
call fails.
Fixes: https://bugzilla.novell.com/show_bug.cgi?id=807850
(thanks to Michal Hocko for investigating investigating and
finding the root cause of the bug)
Reference:
http://lists.freedesktop.org/archives/dri-devel/2013-March/036564.html
v2: Use one variable to store file and inode mapping
since they are the same at the function entry.
Fix spelling mistakes in commit message.
v3: Add reference to the original bug report.

drm/i915: Turn off hsync and vsync on ADPA when disabling crt
properly disabled the hsync/vsync logic at disable time, but neglected
to re-enable them at enable time.
v2: In the enable hook, restore the connector's expected DPMS level
instead of forcing ON. Do this by stashing a back pointer to the
connector in the crt (suggested by danvet) since otherwise it's awkward
to look up.

commit b43decd2c513ae44a5462a1a4c2622f0fa77c9e0 upstream.
If there are no channels, chan would never end up being NULL,
and so the null pointer check would fail.
Solve this by initializing chan to NULL, and iterating over temp instead.
Fixes oops when running intel-gpu-tools/tests/kms_flip, which attempts to
do some intel ioctl's on a nouveau device.

commit 4a35f83b2b7c6aae3fc0d1c4554fdc99dc33ad07 upstream.
Restore crtc->fb to the old framebuffer if queue_flip fails.
While at it, kill the pointless intel_fb temp variable.
v2: Update crtc->fb before queue_flip and restore it back
after a failure.
Backported for 3.8-stable. Restored an atomic_sub removed
in 3.9 ca9c46.

commit 9d1a455b0ca1c2c956b4d9ab212864a8695270f1 upstream.
The eDP output on HP Z1 is still broken when X is started even after
fixing the infinite link-train loop. The regression was introduced in
3.6 kernel for cleaning up the mode clock handling code in intel_dp.c
by the commit [71244653: drm/i915: adjusted_mode->clock in the dp
mode_fix].
In the past, the clock of the reference mode was modified in
intel_dp_mode_fixup() in the case of eDP fixed clock, and this clock was
used for calculating in intel_dp_set_m_n(). This override was removed,
thus the wrong mode clock is used for the calculation, resulting in a
psychedelic smoking output in the end.
This patch corrects the clock to be used in the place.
v1->v2: Use intel_edp_target_clock() for checking eDP fixed clock
instead of open code as in ironlake_set_m_n().
Backported for 3.8-stable. Reverted refactoring in e69d0bc1.
